DAI Signalscan DX is a complete waveform viewing simulation analysis and tightly coupled source code debugging environment for Verilog and mixed Verilog/analog simulation. Signals may be backtraced from the waveform or source code views without need to refer to a schematic. DAI Signalscan provides many different views into the simulation results including waveform, register, source code, design browser, and trace browser. DAI Signalscan, first introduced in 1993, was the first commercially available simulation analysis tool to use database technology to store simulation data.

DAI recently introduced DAI Signalscan DX that includes SST2, a third-generation simulation database technology. The SST2 database is 30 to 50 percent the size of the previous SST database and typically five to 20 percent the size of standard Verilog VCD files. DAI Signalscan DX also includes the Turbo Compression option, which is producing file sizes 1/10 to 1/100 the size of standard Verilog VCD files.
